Hello Ariel,
This is an answer to your 2nd question. Only if the other methods are for ice-breaking, reactivating or relaxing after hours working, thinking, building, sharing, etc., then I might recommend it. Be careful not to take the group out of flow!
To your first question…
For an industrial process, you will have probably a mixture of process oriented minds (engineers) and hand-skilled guys. They both love to build! Though, abstract thinking might be a challenge for both. I had this situation already, so what worked for me was the following (after skills building, 1 h)
1. build yourself at work – ok, this might be criticized not being pure LSP (cause this is modeling reality and not metaphoric), but it worked for me
2. get together with your team, build shared model of the process step. SHARE YOUR PROCESS STEP WITH THE WHOLE GROUP! (the team should share a brief but comprehensible “what is critical for us”)
3. Teams get together with their client or provider in the group and build a shared model, which is now a production chain model
4. integrate in the model the support areas (HR, Quality, Engineering,…). Now you have the whole plant model.
Now you are ready for the real work:
1. Make teams with client-provider pairs and ask them to build together an improvement (small plates).
2. Bring them to the big model and share.
3. Make new client-provider pairs. Build new improvements (avoid building duplicates from previous models)
4. Group now discusses what improvements are feasible or quick to implement.
Hope this helps!
